Book Description
The Symposium on Vertical Reference Systems (VeReS) was initiated on the occasion of the XXII General Assembly of the International Union of Geodesy and Geophysics (IUGG), Birmingham 1999, by Professor Dr. Wolfgang Torge, Past President of the International Association of Geodesy (lAG) and representative of lAG to the Pan-American Institute of Geography and History (PAIGH). The idea was to organise another joint symposium of lAG and PAIGH like the previous one held during the XX IUGG General Assembly at Vienna, Austria, in 1991. Good reasons for such a joint symposium were the great success and the ongoing activities of the Project on the South American Geocentric Reference System (Sistema de Referencia Geocentrico para America del Sur, SIRGAS) being sponsored by lAG and PAIGH since 1993. The SIR GAS Project (Working Group I) had presented a continental South American reference frame of 58 stations during the lAG Scientific Assembly at Rio de Janeiro, in 1997. This reference frame was already adopted by several South American countries as the basis for their new national horizontal geodetic datums (SIRGAS Working Group II). To overcome the problems of the heterogeneous vertical (height) datums between the individual countries, SIRGAS had installed its Working Group III "Vertical Datum" in 1997. As the discussion on the unification of vertical reference systems is also going on in lAG and other bodies of science and practice, it was decided to dedicate the symposium to this topic.

Book Description
An exciting and heart-pounding look at one of Western Canada's most adventurous individuals, known as a pioneer pilot of the heli-ski industry and as the first mountain-rescue pilot in the Canadian National Parks system. Jim Davies is an icon of competence and courage as the first heli-skiing pilot in Canada. But it is his groundbreaking work as a helicopter rescue pilot for Parks Canada that made him a legend to all who worked with him. His stellar career as a pilot overshadowed his other talents as a ski racer and artist. Jim received several awards for his work in mountain rescue, including the Helicopter Association International - Pilot Safety Award of Excellence, the Alberta Achievement Award for excellence in helicopter flying, the Summit of Excellence Award at the Banff Film and Book Festival, and the Robert E. Trimble Memorial Award for "distinguished performance in helicopter mountain flying." He is now retired and living in Banff, pursuing his love of painting and photography.

Book Description
This book addresses the problems of mathematical relations between global and classical coordinate references from the practical applications point of view. It presents a large cartographic and numerical information set, which provides great values for practical and academical use based on the classical Albanian coordinative reference (ALB1986/ALB1987). This information is reflected from the positional point of view in the new modern Albanian satellite reference ALBPOS (Albanian Positioning System) or ALBCORS (Albanian Continuous Operation Reference Stations System). The main purpose of this Monograph is to summarize coordinative references applied in Albania in different periods, both classical and modern. Relevant transformation models between traditional/classical reference ALB1986 / ALB1987 and GNSS satellite reference are presented. The book furthermore recommends the mathematical models of the relationship in plan and height, between the Albanian classical reference and the global/European coordinate references (ITRF, EUREF). It serves to professionals involved in fundamental geodetic works as well as all working with GNSS or developing GIS applications.

Book Description
Surveying a Century Ago As it was based on the principles of geometry and trigonometry, surveying may be may be looked upon as a branch of practical mathematics. Hence, it was necessary that land surveyors and hydrographers should have a fair general knowledge, not only of these subjects, but also of all the subjects comprised by the term mathemat ics. In addition, the knowledge of mathematics required in ordinary chain surveying and levelling was not very extensive but in geodetical work, the highest mathematical ability and great organising power were required for a proper conception and supervision of the operations (Threlfall, 1940). Only small area of a few hundred square kilometres can be accurately mapped and surveyed without a frame work, since no difficulty is encountered because of Earth-curvature. In the past, especially in hydrography due to the type of work, surveying was carried out on the principles of ordinary practice, but in a very rough man ner, rapidity of execution being of paramount importance, the permissible error was sometimes large. The relative positions of the main surface features were obtained by aid of portable instruments, such as sextants and lead lines, tide poles, and logships. Sketching, just like military surveying was often filling in the smaller detail. In contrary, survey works done by the national mapping agencies (NMAs) were of a higher-level, and comprised the delimitation of boundaries as well as topographical surveys.
